Description

Technical Field

[0001] This utility model relates to the field of positioner technology, specifically a U-shaped positioner. Background Technology

[0002] A positioner is a specialized welding auxiliary device primarily used for repositioning workpieces in rotary welding operations to achieve the ideal processing position and welding speed. It can be used in conjunction with manipulators and welding machines to form an automated welding center, or for workpiece repositioning during manual operations. The applications of positioners are not limited to welding; they can also be linked with other equipment to improve production efficiency and quality. For example, it can be used in conjunction with welding robots to achieve automated welding of complex workpieces by precisely controlling the position and angle of the workpiece, thereby improving production efficiency and welding quality.

[0003] However, some positioners have relatively simple mechanisms, and during the positioner operation, they can only perform flipping motion on a single workpiece, which cannot meet the synchronous positioning of two workpieces. Moreover, the positioner operation is in a single axial direction, which makes it difficult to perform the flipping motion after rotation when facing different processing angles, resulting in low flexibility. Summary of the Invention

[0004] In order to solve the problem of single-direction shifting and changing of work positions, the purpose of this utility model is to provide a U-shaped positioner.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a U-shaped positioner, including a base, a bracket fixedly connected to the top of the base, rotating side plates rotatably connected to both ends of the bracket, a clamping mechanism movably provided at the top of each of the two rotating side plates, a pulley fixedly sleeved through the bracket at one end of each of the two rotating side plates, a synchronous belt sleeved on the outer surfaces of the two pulleys, a first motor fixedly mounted at one end of one of the pulleys, a support plate fixedly mounted on the middle outer surface of the base, a first gear and a second gear rotatably connected to the top of the support plate respectively, the outer surface of the first gear meshing with the outer surface of the second gear, a rotating seat plate fixedly connected to the top of the first gear, the top of the rotating seat plate fixedly connected to the bottom end of the bracket, a second bevel gear fixedly connected through the support plate at the bottom end of the second gear, a first bevel gear meshing with the outer surface of the second bevel gear, one end of the first bevel gear rotatably connected to the inner wall of one end of the support plate, a second motor fixedly mounted on one side outer surface of the base, the output end of the second motor fixedly connected to one end of the first bevel gear.

[0006] Preferably, the clamping mechanism includes two slide rails, the bottom ends of which are fixedly connected to the top sides of the rotating side plate, and movable plates are slidably sleeved on the outer surfaces of the two slide rails. A transmission plate is rotatably connected to the middle of the top of the rotating side plate, and a top plate is rotatably connected to the top of the transmission plate. Connecting plates are rotatably connected to both ends of the transmission plate. One end of each of the two connecting plates is rotatably connected to the top of the two movable plates. Cylinders are fixedly installed on both sides of the top of the rotating side plate, and the output ends of the two cylinders are fixedly sleeved to one end of each of the two movable plates.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This utility model achieves the dual-station flipping and rotation function of the workpiece by setting the transmission of the first gear and the second gear, as well as the transmission of the pulley and the synchronous belt, so that the workpiece can be in the ideal processing position, saving the time of clamping and adjusting the workpiece.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-3 As shown, this utility model provides a U-shaped positioner, including a base 1, a bracket 11 fixedly connected to the top of the base 1, rotating side plates 12 rotatably connected to both ends of the bracket 11, clamping mechanisms 3 movably provided at the top of each of the two rotating side plates 12, a pulley 13 fixedly sleeved through the bracket 11 at one end of each of the two rotating side plates 12, and a synchronous belt 14 sleeved on the outer surface of the two pulleys 13, a first motor 15 fixedly mounted at one end of one of the pulleys 13, a support plate 16 fixedly mounted on the outer surface of the middle part of the base 1, a first gear 17 and a second gear 18 rotatably connected to the top of the support plate 16 respectively, the outer surface of the first gear 17 meshing with the outer surface of the second gear 18, a rotating seat plate 19 fixedly connected to the top of the first gear 17, and the top of the rotating seat plate 19 being connected to the bracket 11. The bottom end is fixedly connected to the support plate 16. The bottom end of the second gear 18 passes through the support plate 16 and is fixedly connected to the second bevel gear 20. The outer surface of the second bevel gear 20 is meshed with the first bevel gear 22. One end of the first bevel gear 22 is rotatably connected to the inner wall of one end of the support plate 16. A second motor 21 is fixedly installed on one side of the outer surface of the base 1. The output end of the second motor 21 is fixedly connected to one end of the first bevel gear 22. The output rotation of the first bevel gear 22 by the second motor 21 can drive the second gear 18 to rotate the first gear 17. The rotating first gear 17 drives the bracket 11 at the top of the rotating seat plate 19 to rotate horizontally. Then, under the synchronous transmission of the two pulleys 13 and the synchronous belt 14, the two rotating side plates 12 on both sides of the bracket 11 are synchronously flipped, realizing the flipping and rotation of the two workpieces.

[0016] The clamping mechanism 3 includes two slide rails 31 and a clamping plate 36. The bottom ends of the two slide rails 31 are fixedly connected to the top sides of the rotating side plate 12, respectively. Movable plates 32 are slidably sleeved on the outer surfaces of the two slide rails 31. A transmission plate 34 is rotatably connected to the middle of the top of the rotating side plate 12. A top plate 35 is rotatably connected to the top of the transmission plate 34. Connecting plates 33 are rotatably connected to both ends of the transmission plate 34. One end of each connecting plate 33 is rotatably connected to the top of the two movable plates 32, respectively. Cylinders 30 are fixedly installed on both sides of the top of the rotating side plate 12. The output ends of the two cylinders 30 are fixedly sleeved to one end of each movable plate 32, respectively. Driven by the cylinders 30, the transmission plate 34 is provided with rotational power by retracting and pushing one of the connecting plates 33. Thus, the rotating transmission plate 34 drives the two movable plates 32 to slide linearly along the outer surfaces of the two slide rails 31, thereby achieving synchronous clamping motion of the two clamping plates 36.

[0017] The bracket 11 is in the shape of an "I" and the two ends of the bracket 11 are of the same length. The two pulleys 13 are mirror-distributed. The size of the first gear 17 is larger than that of the second gear 18. The size of the second bevel gear 20 is the same as that of the first bevel gear 22. The "I"-shaped bracket 11 facilitates the synchronous rotation of the two rotating side plates 12 through the same two ends, realizing the rotational movement of the two workstations and reducing the gravitational influence caused by rotation. The two pulleys 13 are mirror-distributed so that the rotation of one pulley 13 can transmit the same force to the other pulley 13, so that the two pulleys 13 can rotate the two rotating side plates 12 synchronously under the transmission of the synchronous belt 14. The second bevel gear 20 of the same size is the same as that of the first bevel gear 22 to ensure the maximum transmission of rotational force, so that the second gear 18 can transmit the first gear 17 to the maximum extent. The larger size of the first gear 17 is to increase the rotational torque on the rotating seat plate 19, thereby better driving the bracket 11 to rotate horizontally.

[0018] The two slide rails 31, the two moving plates 32, and the two connecting plates 33 are all mirror-distributed, and the two clamping plates 36 are both "L"-shaped. The purpose of this is to facilitate the application of force to one of the moving plates 32 by the cylinder 30, while the connecting plate 33 applies the rotational force of the transmission plate 34 to the other moving plate 32 with the same clamping force, thus ensuring that the clamping force of the two clamping plates 36 is consistent.

[0019] Working principle: When repositioning is required, the second motor 21 at the top of the base 1 is started. The output end of the second motor 21 drives the first bevel gear 22 to engage. The rotating first bevel gear 22 drives the second bevel gear 20 to rotate, thereby driving the second gear 18 to rotate. The rotating second gear 18 drives the first gear 17 to rotate horizontally, thereby driving the rotating seat plate 19 at the top of the first gear 17 to rotate. The rotating seat plate 19 drives the bracket 11 to rotate 360 ​​degrees horizontally. During the rotation of the bracket 11, the operator can start the first motor 15 at one end of the base 1 to drive one of the pulleys 13 to rotate. The rotating pulley 13 drives the two rotating side plates 12 to flip under the transmission of the synchronous belt 14, thereby realizing the rotational repositioning of the two axes.

[0020] When it is necessary to fix the displaced target, place the displaced target on the top of the top plate 35, start the cylinder 30, and the output end of the cylinder 30 drives one of the moving plates 32 to retract. The retraction force causes one of the moving plates 32 to slide linearly along the outer surface of the slide rail 31. As a result, the linearly moving moving plate 32 applies force to one end of the transmission plate 34 with the help of the connecting plate 33. The transmission plate 34 rotates, thereby driving the connecting plate 33 at the other end to drive the moving plate 32 to move linearly in a relative direction along the outer surface of the slide rail 31, thereby realizing the clamping movement of the two clamping plates 36, which makes it convenient for the operator to clamp and fix the displaced workpiece.

[0021] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
